By any chance would there be a way to get an autographed copy ?


Edit : Out of curiosity, I don't remember if TI-Planet and Omnimaga are cited in the book ?
(I just noticed Persalteas ("Louis Becquey") got featured on the back page, congratz )

Uh, let me reply quickly (I believe I'll have time to reply more deeply later) :
I see you're using BetterLuaAPI (), however it's been updated in FormulaPro (maybe I forgot to update it on its repo ), and here's the new version, using a good gc :

l_beta = string.uchar(946)
l_omega = string.uchar(2126)
sup_plus = string.uchar(8314)

The main difference, again, is about the gc usage.
Passing gc to the functions is the *only* way to do things well


I'll get back to your main problem soon (also calling jim )

Yes, sorry, we can't be sure, but we'll try
Now that we know ho to dump them, it might even be more interesting with the 84 emulation if it's there !

Well, as a Omnimaga newser care should be taken for not making Omnimaga.org as a bare redirection to TI-Planet by editing the links in the posts. It would  help to miss-interpreting your posts as being mainly advertisements for TI-Planet.

Sure. In important posts tho, I take the required time to make it as good as possible, here, is was just a reference to another program I had in mind, obviously not an ad.

Indeed the graphics are beautiful, but you may have not heard of this on , which is pretty nice too graphics-wise
(well, it's based of the official one)

Yeah I also thought when I first encountered that, that the polarization could be the cause

Arg, I bidded for $260 but a calculator collecter (according to his bidding history) got them by sniping higher....
